Fire resistant systems

Cable supporting systems with maintained funcionality in fire

The cable inlet is mounted to the box using a standard route, most often using separate cable clamps 67xx, Omega or Dobrman.

You can also use the box as a non-standard load-bearing structure (eg via wiring pipes ...)

For power and data uses

in three sizes (KSK 100, KSK 125, KSK 175)

possibility of variant box with fuse (thermal and current)

MDS mounting plate is used to fasten the cable trays

The use of cables for KSK boxes depends on the type of construction that the boxes are part of. For information on applicable cable types (or without limitation = standard route), see the catalogue Systems with maintained functionality in fire from KOPOS KOLIN a.s.

Own test in the fire chamber

What is necessarily to do?

Preparation of systems before assembly (joining and cutting of trays, ladders, pipes, etc.) Preparation of profiles and threaded rods at required lengths

Assembly of systems into the chamber - insertion of systems together with cables into the fire chamber

System balancing - using chains to the required load

Electrical connection of cables - to clamp all the cores with terminals

Self-test PO – duration up to 120 minutes

After the PO test, a test report is issued by the examiner and a statement is issued on the test. These documents are sent to EZÚ and KOPOS KOLÍN a.s. a certificate is issued that allows us to sell the systems.

If the cable route is fixed directly to a building structure from a material such as concrete, brick, aerated concrete or a steel support structure, only such anchorages must be used for the connection to the structure with respect to:

The type of material used

The method of assembly used

Required duration of heat loading

Required time of functionality in fire

Mechanical load with carrier and fixing structure with cables

To attach the cable route, you can use for example:

screw joints

riveted joints

welded joints

The suitability of fastening for the purpose must be proven by a test or documented by a static calculation.

Conclusion:

When installing fire-resistant routes, we should always ensure that everything is properly installed in accordance with the standard and installation instructions, procedures and descriptions listed in the producer´s catalog.

It should always be about the safety and protection of human or other sources from the devastating effects of the fire.
